IMPROVEMENT IN LUBRICATORS.

Specification forming part of Letters Patent No. 205,524, dated July 2,1878; application tiled Julie 1, 1878.

To all whom it may concern:

Be it known that we, HARMAN BROCIOUS, HIRAM ELIJAH BENSINGER, and SAMUELWRAGG, of Raven Run, in the county of Schuylkill and State ofPennsylvania, have invented new and useful Improvements in Lubricators,of which the following is a specification:

Our invention relates to certain improvements in means for automaticallylubricating the piston and piston-rod, valve and valvestem, and otherparts of a steam-engine.

The invention consists in a novel arrangement of an oil-cup orlubricant-holder, and a novel construction and arrangement of devicesemployed in connection therewith, whereby thelubricant is automaticallysupplied at regular intervals and in uniform quantities; and, further,in certain details of construction and arrangement of devices forregulating the quantity of lubricant and frequency of supply.

In carrying out our invention the lubricantholder is arranged,preferably, on the top of the steam-chest, and communicates with ar'otary valve and a conduit leading to said steamchest. The valve isrotated by gearing which receives motion through a ratchet, pawl, andlevers connected with the slide-valve stein, so that at every stroke ofthe slide-valve the rotary valve receives motion, and after a certainnumber of such strokes (which number may be regulated at the pleasure ofthe person in charge of the engine) the lubricant is supplied by therotary valve.

The accompanying drawing illustrates a mode of carrying out ourinvention.

Figure 1 is a side view of a portion of acyl inder and steam-chest withour improvements applied thereto. Fig. 2 is detail view, partly insection, hereinafter referred to.

Similar letters of reference indicate corresponding parts.

The cylinder A and steam-chest B, portions of which are shown in Fig. 1,are of any ordinary or suitable construction. The oil-cup orlubricant-holder O is attached to the upper end of a tube or pipe, D,the lower end of which enters the steam-chest B. At a suitable point inthe pipe D, between the cup 0 and the steamchest, is a seat, 6, in whichworks a rotary valve, which is here shown asconsistin g of a round plug,F, provided with a recess, f. (See Fig. 2.) To the stem of this rotaryvalve F, or the end of the plug which forms the valve, is attached agear-wheel, G, which meshes into and is driven by a gear-wheel, H,attached to a shaft, h, journaled in bearings t on an arm, J, andcarryinga ratchet-wheel, L.

The arm J may be arranged in any suitable manner. It is here shown asattached to and supported by the pipe D, extending outward therefrom,and carrying a slot-ted standard, K.

At the lower end of the slotin the standard K is pivoted the lower endof a slotted bar or lever, N. A pawl, M, is pivoted in the slot of thelever N, with its toe or point engaging with ratchet L. The pawl M worksin and is guided by the slot in the standard K. To the upper end of thelever N is pivoted the upper end of a rod or pitman, P, the lower end ofwhich is attached, by means of a clamp, Q, to the rod or stem R of theslide-valve.

The operation is as follows: As the valvestem It moves outward the pawlM slips over the ratchet L and engages with another tooth, and, as thereverse motion of the rod takes place, the pawl M turns the ratchet adistance equal to the length of one or more teeth, and, through thegearing G H, gives motion to the rotary valve F, so as to carry therecess f, containin g the lubricant, in a direction toward the lower endof the pipe D. Thus, at every revolution of the valve F, a certainquantity of lubricant is taken from the cup or holder 0 to thesteam-chest B, and from thence distributed with the steam throughout thesteamchest and the cylinder.

There may be any desired number of recesses f in the valve F, so as tosupply the lubricant more frequently than once for each revolution.

The speed of rotation of the valve F may be increased or diminished byadjusting the pivot 19 of the pitman 1? either higher or lower in theslotted lever N ,-so as to cause the-pawl to en gage with a greater orless number of teeth on the ratchet and turn it more or less at eachstroke of the valve-rod It.

We are aware of the existence of a lubricating apparatus consisting ofan oscillating or revolving oil-cup, having a perforated bottom andturning on a perforated plug fitted to the journal-box of the shaft tobe lubricated. In this case the oil-cup receives its motion from theshafting by a worm and screw and other mechanism.

Having thus described our invention, what we cl. iin as new, and desireto secure by Letters Patent, is-

1. The combination of the rotary valve F, having the recess f, and thetube D, having the valve seat or tube 0, with the oil-cup orlubricantholder O, as and for the purpose set forth.

2. The combination of the gearing G H, ratchet L, pawl M, and lever Nwith the oil- 11' HARMAN i nnooions.
